Method for attaching a porous metal layer to a metal substrate

A method for attaching a porous metal structure to a metal substrate, the method comprising:

• providing a metal substrate comprising a metal selected from the group consisting of cobalt, cobalt alloy, titanium and titanium alloy;
• providing a binding mixture;
• providing the porous metal structure;
• applying the binding mixture to the porous structure by means selected from the group consisting of spraying, and dipping;
• placing the porous structure against the substrate such that the binding mixture is disposed between the metal component and the porous structure, thereby forming an assembly;
• and
• applying heat and pressure to the assembly to metallurgically bond the porous structure and the substrate.

A method for attaching a porous metal structure to a metal component of an orthopedic implant, the method comprising:

• providing a metal component comprising a metal selected from the group consisting of cobalt, cobalt alloy, titanium and titanium alloy, said metal component having a desired shape and a bone contacting surface;
• providing a binding mixture;
• providing the porous metal structure in a desired shape;
• applying the binding mixture to the porous structure by means selected from the group consisting of spraying, and dipping;
• placing the porous structure against the bone contacting surface of the metal component such that the binding mixture is disposed between the metal component and the porous structure, thereby forming an assembly;
• and
• heating the assembly to metallurgically bond the porous structure and the metal component.
